This one looks a bit more easily actionable than the swarm of intermittent timeouts and crashes. The test uploads a green texture, renders it with a quad and read-backs expecting green but getting almost-green. Not sure if there is some kind of precision loss/compression in the driver or if something is setup to work in the wrong color space. Perhaps we only need some fuzzing?

Bug 1293143 looks very similar.

Bulk assigning P3 to all open intermittent bugs without a priority set in Firefox components per bug 1298978.
